Why are my Purchase Orders with negative values not matching GRNs?
GRNs (Goods Received Notes) are not designed to handle negative quantities because goods cannot be received in negative amounts. The system’s matching process also prevents negative values from being matched directly to invoices.


This will leave the Purchase order incomplete as the line will remain unmatched


How can I resolve this issue?
To resolve this, the purchase orders need to be amended by removing any negative lines. Once corrected, the matching process will function as expected


Please note if the amount is negative and the documents are matched on quantity rather than amount, this can be submitted. Conversely if the document matching is by amount rather than quantity, you cannot match negative values at this time. This applies to matching of all documents.
